WoWhead Tooltips
It's never been easier to add Wowhead tooltips to your site.[list=1]
Add this piece of HTML code in the section of your page:
You are done!
[/list]
Wowhead links found on your site will now sport a
tooltip and an
icon. The following pages are supported: achievement, profile, item, npc, object, spell, quest. In Mists of Pandaria, we added some spiffy things to our tooltips: icons show up by default, you can customize the colors of your links, and easily rename them!
With Wowhead tooltips, you can also link to any
Hearthstone card in our database! Check out our
Hearthstone Tooltip page for more details.
